基于生态足迹的德阳市耕地脆弱性研究

A Study of the Fragility of Cultivated Land in Deyang Based on Ecological Footprint

  • 摘要: 耕地是人类社会发展的基本条件和物质基础,耕地的脆弱性研究是保持耕地可持续发展的重要手段。通过引入生态足迹模型,对德阳市近10年来耕地的生态足迹、脆弱性指数变化进行分析,得出德阳市近10年来耕地的可持续发展和生态方面的现状。结果表明德阳市耕地:①生态足迹呈缓慢下降趋势。②生态承载力呈下降趋势,下降幅度较大。③生态赤字逐年严重,跟生态承载力的下降有很大的相关性。④面临生态危机的可能性增大,耕地呈现出脆弱状态,分析得到的耕地脆弱性结果,为德阳市耕地的可持续发展现状提供一个参考。

     

    Abstract: The arable land was the basic condition and material foundation of the development of human society,and the study of the fragility of arable land could be an important means to keep the cultivated land sustainable.By introducing the ecological footprint model,an analysis was made of the changes of ecological footprints and frangibility indexes of the cultivated land in recent ten years,and the ecological situation of the arable land was obtained in recent ten years.The results showed that ① ecological footprints showed a slow downward trend.②The ecological carrying capacity was decreasing,and the descending amplitude was large.③ The ecological deficit was getting serious,which had a great correlation with the decline of ecological carrying capacity.④ The possibility of ecological crisis was increasing,the arable land presented a fragile state.A reference could be provided for the sustainable development of local arable land.
